WEBVTT Kind: captions Language: en 00:00:00.000 --> 00:00:09.760 [Music] To see is to understand. So the more we  see of a cell, then the better we understand it.   00:00:09.760 --> 00:00:15.360 All fields within mathematics use the same  approach. We recognize a problem, we analyze   00:00:15.360 --> 00:00:22.040 it and then we study the resulting theory.  The battery is key to more efficient and   00:00:22.040 --> 00:00:28.600 more climate friendly energy transition  and mobility transition. We are studying,   00:00:28.600 --> 00:00:35.520 what makes religion the motor of political or  social change from antiquity to the present 00:00:35.520 --> 00:00:44.480 day. We see, that about one in six  couples are infertile and the reason   00:00:44.480 --> 00:00:47.560 for the infertility lies just as  often with the man as with the 00:00:47.560 --> 00:00:54.200 woman. We make biological samples visible. 00:00:54.200 --> 00:01:01.400 We use state-of-the-art cryoEM technology. We can enlarge them to one ten-millionth of a millimetre. 00:01:01.400 --> 00:01:10.360 Every part in mathematics has its own  language. We network between fields like geometry,   00:01:10.360 --> 00:01:17.080 algebra, analysis and their applications  to find answers to fundamental questions.   00:01:17.080 --> 00:01:22.400 Lithium-ion batteries are used everywhere and  by everybody. We not only deploy them in electric   00:01:22.400 --> 00:01:28.960 vehicles, they are also found in smartphones  and laptops. We need to address material and   00:01:28.960 --> 00:01:35.760 resource diversity and develop sustainable supply  chain. For many of these men actually their semen   00:01:35.760 --> 00:01:41.400 analysis looks completely normal, they have sperm,  enough of them, they swim, they look normal, but yet   00:01:41.400 --> 00:01:46.400 they're infertile. And what we found when  we look closer at them, actually, we see that   00:01:46.400 --> 00:01:53.320 the sperm are unable to penetrate the eggs coat  on their own and this leads to their infertility.   00:01:53.320 --> 00:02:00.840 Why do people pray to a God and why do they  use war for defending their faith, and why do   00:02:00.840 --> 00:02:08.240 they give unconditional help to each other. Today  we face, in fact, great challenges. To find answers   00:02:08.240 --> 00:02:13.600 to the big questions, we sometimes have to do  research in the smallest areas to the atomic   00:02:13.600 --> 00:02:20.400 level. This enables us, for example, to understand  how diseases arise and most importantly, how they   00:02:20.400 --> 00:02:28.160 can be cured. Together with chemists,  biologists, physicists and engineers, we are   00:02:28.160 --> 00:02:34.520 working on recycling and reusage of batteries  and its components. New findings in mathematics   00:02:34.520 --> 00:02:40.240 are not standalone results, they often lead the  way to unexpected breakthroughs in other branches   00:02:40.240 --> 00:02:46.640 of science. So we've developed a test which can  identify very rapidly this type of infertility,   00:02:46.640 --> 00:02:52.120 that some men suffer. A test which can  potentially be used all over the world. Mobility   00:02:52.120 --> 00:02:57.400 transition and energy transition belong to the  so-called mega challenges. We can only overcome   00:02:57.400 --> 00:03:04.320 them by working together in research alliances: nationally and internationally. The range   00:03:04.320 --> 00:03:13.920 of research, being carried out at the University  of Münster is really enormous. Every answer leads   00:03:13.920 --> 00:03:25.520 to new research questions and every research  question needs clever minds to work on solutions. 00:03:25.520 --> 00:03:29.680 [Music]
